ATTACHMENT FOR SUBMABINE ARMOR.

Specification of Letters Patent. 'Pwgent gd App, 1933 Application filed December a, 1910.

Serial No. 595,848.

To all whom it mag concern:

Be it known tliat'L CHESTER E. MAGDUF- ran, a citizen of the United States, residing atthe borough of Manhattan, city, county, and State of New York, have invented a new and useful Attachmentfor Submarine Armor, of which the following is a specification.

My invention relates to adevice adapted to be secured to the armor worn by submarinedivers, and provided with swinging connections for the flexible tubes or hose through which air is supplied from above water to the diver and for the discharge of the exhaled or vitiated air from. the-armor, and the objects of my invention are (1) to allow a free movement of the hose ortube connections while the diver is descending'or ascending, or while at work at the bottomamong Wreckage, so as to prevent twisting of the tubing or any undue strain upon the same or the connections, and (2) to provide an intervening air chamber between the armor and the air'supply tube, from which air chamber a port of small diameter comlnunicates with the interior of the armor so that a regulated and uniform-supply of air will be conveyed to the diver.

In the accompanying drawings Figure 1 is a vertical section of my improved attach mcnt. Fig. 2 is a section at the line a an, of Fig. 1 and Fig. 3 is an elevation of the upper portion of a submarine armor illustrating where my attachment is connected to the same.

Similar reference numerals refer parts throughout the several views. I

1 is a cylinder having flat heads 1 screwed thereon at opposite sides, and a fiangedbase, there being oppositely disposed circular to like openings in each of the cylinder heads 1,

which openings are. central of the cylinder 1 and of corresponding diameter.

Within the cylinder 1 and arranged centrally therein is a wall or partition preferably comprising a circular disk 2 having in tegral tubular cylindrical projections 3 at its center at each side, 'which projections extend through the said openings in the heads 1? at the respective sides of the cylinder and are.

provided with annular flanges 4 at such distance from the sides of the disk as to fit in and occupy the said openings in the cylinder ections 3,

mension: that their On the outer surface of the cylinder heads 1 at each side of the cylinder and surrounding said openings in the cylinder heads at a predetermined distance therefrom arerqircular projections 5 interiorly screw-threaded;

The outer ends of the tubular projections 3 are exteriorly screw-threaded, and upon the same are screwed tubular elbows 6 which are exteriorly screw-threaded at their free ends and provided with annular ribs or flanges 7 for the attachment of flexible tubing 7* (see Fig. .3) for the supply and discharge or air. Set screws 8 are preferably employed'to prevent the elbows" 6 turninp upon thescrew-thi'eads of the tubular proafter they have been screwed to place.

The periphery of the dish; 9: is provided with a screw thread and upon this is screwed the flat sided rings 9, which are of such dipcripheries come closely adjacent to the interior circular surface of the cylinder 1, but not in contact therewith. These rings 9 are rabbeted on their meeting surfaces leaving an annular recess between them at the top, and placed a suitable packing 10 which fills such recess and extends therefrom into the space between the peripheries of the rings 9. and the interior circular surface of the cylinder 1, entirely filling such space and sealing the air chamberll thus formed. in the cylinder-1 at either side of the disk 2 one from the.

other.

The bore in the tubular-member 3 extending at either side of the disk 2 terminates inwardly preferably somewhat conically and at a point slightly. within said disk Through these tubular project-ions 3 at a point between the annular flanges 4c thereon the disk 2, and consequently in tliatpart within the air chambers 11 are bored spaced apart openings 12 in a circular range. Parts 13 extend through the base of the cylinder and communicate between the I'bSp9C- tive air chambers 11 and the interior of the armor 15 through 0 enings 14 in the armor. Through the flanged portion 16 of the base within this recess issuch openings and are revoluble-therein.

of the cylinder are spaced apart bolt holes,

through which are passed the screw threaded bolts 17 which screw into screw threaded holes in the armor 15.

A circular packing gland 18 surrounds the tubular projections 3 at each side of the cylinder heads 1; there being intervening the screw threads on the interior surfaces of said circular projections 5. There are packing rings 19 between the glands 18 and the cylinder heads 1*. Each of the glands 18 has an annular recess 21 in its inner surface. Within each of-these recesses 21 there is a presser ring .22 and helical spring 23, the springs bearing upon the presser rings and forcing them against the packing rings 19.

It will be readily seen'that the liability of injury to the hose or flexible tubing while the diver is descending or ascending, or while attending to his duties at the bottom of the sea is obviated-by the employment of my invention: and that the air required by the diver while down is supplied to him in uniform regulated quantity. I

The air chambers 11 withinthe cylinder 1 on both sides of the disk 2 being alike as are also the joints and connections it is immaterial which side'is used for the supply ayid which side for the exhaust, .but it willbe readily understood that the tube conveying air for the diver will be connected with a source of supply above water, while the tube conveying away the exhaled or vitiated air discharges into the atmosphere.

I claim as my invention;

1. The combination with an armor for submarine divers, of a stationary hollow body secured directlyto said armor, passageways for air between the interior of said hollow body and the interior of said armor, and swinging connections secured to said hollow body through which air is supplied to the diver and v'itiated air discharged from the armor.

2. The combination with an armor for submarine divers and hosefor air, of a hollow body for connection with the armor having openings for air, series of revoluble devices within and projecting from said hollow body and adapted for connection with the hose and between and through which body and revoluble devices are passageways for air. I j

3. The combination with an armor for submarine divers and hose for air, of a stationary hollow body secured directly to the said armor, passage-ways for air between said ,hollow body and the interior of the armor, a revoluble partition member or wall mldway within the hollow body dividing the same into two chambers, revoluble tubular members extending from the partition member in opposite directions through the said body to connections with the hose and the tubular members having openings into said chambers.
